Read above dude, they've ALWAY's been able to do that, but it takes quite a while to accelerate up to those speeds.
As I said, the problems regarding light speed arne't too much of a problem on EA ships, since they use Ion\Particle engines, whcih can only propel it so fast.

Yeah, but they did it in like a few seconds, how did they accelerate so fast?

man, pseudoscience at its best

engines limit accelerations not velocity. Given enough fuel and time, even the space shuttle could almost reach the speed of light. Hell, Sonic the hedgehog could do it.

This whole concept of a speed limit in space is added for gameplay value. If you've had elementary physics, you should know that. If you haven't, you shouldnt be speculating.

Hi,

While NegspectahDek is perhaps being a bit harsh there is something to be said for a few of you folks reading a basic physics primer. Something dealing with Newton's laws at a basic level should do, though surely no-one here is young enough not to have covered them in school.

Bye,

Dave

Oh no, let me think, do I have a physics grade like that, mmm, I don't know, does A level physics count in this?
Yes engines limit acceleration, but the power of the engine (for want of a better word) also limits top speeds- the ship cannot move faster than the molecules coming out of the rear of the engine.

Acctually there is a speed limit in space!!!!

let's say you are standing at on mplace speed is 0m/s and you üut you're thrusters to max....then particels will come out of the engine let's say @ 3000m/s....
now we have thrusted our spaceship to a speed of 3000m/s and we turn off the engines.....
if you turn the engines to max again the speed of the particel will be 0m/s so there is no force to push you forward...

common misconception

the way you're thinking about it is that the exhaust particle need to push against something behind the ship in order to produce thrust. They dont. The fact that they leave the back end of the ship is enough to produce the thrust. In actuality, its the exhaust pushing against the thrust chamber that produces the thrust. As long nothing else effects the ships movement, nothing can limit the ships speed

The only possible way a ship can travel at high speeds and avoiding everyone inside getting crushed is if something is pushing the ship. It goes something like if the ship is accelerating by itself there is a force that sort of pushed against the ship (no it's not friction) it doesn't slow the ship down but is like squashing it. However if something is pushing the ship the force goes on whatever is pushing it. This might apply to some types of engines in b5 i don't know.

And Driller have u heard of Enertia (i think thats how u spell it)

And another thing is say a ship approaches the speed of the light the mass that is gained is astronomical and of course I don't think a human body weighing several ****** tonnes could handle that kind of mass either...

anyone who said engines limit speeds are wrong...I dont care if Ur A levels, universty year 2 physics here....

Sigma957, at nearly the speed of light everything gains more mass,but not matter, so it would weigh the same.

also, to an observer, it seems like your mass is reaching infinity, but to you, nothing changes. If you really want to get down to it, as you approach the speed of light, time slows down, and you shink. relativity isnt the realm of pseudoscientists

what I think is, the ship or yourself dont actually shrink/gain mass/stretch... it only APPEARS to do so, since the speed of light can't SHOW you ships moving faster than the speed of light, it distorts the image.

So we CAN go faster than the speed of light, we just wont see it happening, since the speed of light is kind of the limit of our visual odometer.

Einstein didint know what he was talking about...

There's one thing no one has mentioned so far: singularity. At high speeds the mass-energy becomes so huge it starts to stretch space-time more and more strongly (of course this happens at zero speed too). Just before the light barrier mass-energy (E=mc^2) relation to volume reaches infinity, the ships collapses into a singularity, an event horizon forms and that what once was a ship turns into a black hole (and it's moving at incredible speed...). I'm not sure how stable the singularity would be (let's ask Mr. Hawking ), it might explode producing a giant flash of gamma radiation and particles (first pions, myons, mesons etc. by time they turn into stable particles like neutrinos, photons, electrons, positrons...) It might also cause some trouble since it stretces time-space: think of an Einstein-Rossen bridge (=wormhole) which opens nearby us, swallows half of the planet and then collapses. Not a very pleasant wiev. But I still love theoretical physics too .

The speed of light is the limit, because at the speed of light everything turns into energy. The reason Einstein falled was he was bored, he already knew all that so he didnt do the work.

Tachyons dont travel trough normal space do they?
in normal space light is the fastes thing there is

feel free to perforate my theory
